Let's make the equation.
2(N+9)=6
Let's divide both sides by 2.
n+9=3
Now subtract 9 from both sides.
n=-6
So, the number is -6.
The correct answer is a I think is correct
Answer:
its 8
Step-by-step explanation:
because you take away the negative sign
Volume of sphere = 4/3 x pi x r^3
904.32 = 4/3 x pi x r^3
Divide both sides by 4/3
678.4 = pi x r^3
Divide both sides by pi:
216 = r^3
Take the cubic root of both sides
R = 6
We have that
<span>y=1/2x-3
1) the slope of this line equation is m=(1/2)
2) the coordinates of the y intercept are
for x=0
y=-3
point (0,-3)
3)</span>the coordinates of the x intercept are
for y=0
0=(1/2)x-3------> (1/2)x=3----> x=6
point (6,0)
<span>if the line is dilated by a factor of 3
then
</span>y=1/2x-3--------> 3y=3*[1/2x-3]-----> 3y=(3/2)x-9
3y=(3x-18)/2-------> y=(3x-18)/6--------> y=(3/6)x-18/6
y=(3/6)x-18/6
so
1) the slope of this line equation is m=(3/6)-----> 3/6=1/2
2) the coordinates of the y intercept are
for x=0
y=-18/6-------> y=-3
point (0,-3)
3)the coordinates of the x intercept are
for y=0
0=(3/6)x-18/6------> (3/6)x=18/6----> x=18/3------> x=6
point (6,0)
therefore
the equation of the line
y=1/2x-3 is the same that the equation of the line y=(3/6)x-18/6
<span>the equation does not change because the slope and the x and y intercepts do not change either</span>
